xfs_scrub: admin control of automatic fsck [v30.11 1/2]
Now that we have the ability to set per-filesystem properties, teach the
background xfs_scrub service to pick up advice from the filesystem that it
wants to examine, and pick a mode from that. We're only going to enable this
by default for newer filesystems.
This has been running on the djcloud for months with no problems. Enjoy!
